Ques:- What is the difference between event.stopPropagation and event.stopImmediatePropagation?
Asked In :-
infiniX (India), finoux solutions,
Right Answer:
`event.stopPropagation` prevents the event from bubbling up to parent elements, while `event.stopImmediatePropagation` not only stops the event from bubbling but also prevents any other event handlers on the same element from being executed.
`event.stopPropagation` prevents the event from bubbling up to parent elements, while `event.stopImmediatePropagation` not only stops the event from bubbling but also prevents any other event handlers on the same element from being executed.
Comments
event.stopPropagation() allows other handlers on the same element to be executed, while event.stopImmediatePropagation() prevents every event from running. For example, see below jQuery code block.
Hide Copy Code
$("p").click(function(event){
event.stopImmediatePropagation();
});
$("p").click(function(event){
// This function won't be executed
$(this).css("background-color", "#f00");
});
If event.stopPropagation was used in previous example, then the next click event on p element which changes the css will fire, but in case event.stopImmediatePropagation(), the next p click event will not fire.

Ques:- What is a Virtual Network in Azure and how is it configured
Asked In :-
Bhanguz, Travanleo Info Solutions India, Artech Infosystems, Anlage Infotech (I), Aris Global Software, Systematix Infotech, Comviva, LPG, Nohitatu, ACS IT SOLUTIONS,
Right Answer:
A Virtual Network (VNet) in Azure is a logically isolated network that allows Azure resources to securely communicate with each other, the internet, and on-premises networks. It is configured by defining the address space (IP range), creating subnets, and setting up network security groups (NSGs) to control traffic. Configuration can be done through the Azure portal, Azure CLI, or Azure PowerShell.
